An automatic ice making machine includes a refrigeration system comprising a compressor, a condenser, an evaporator and an expansion device; a water system comprising an ice forming surface in thermal contact with the evaporator; and a control system comprising i) an on/off selector that causes the control system to either operate the compressor and water system so that the ice making machine automatically makes ice, or shuts the machine off until manually turned on; and ii) an automatic restart selector that causes the control system to shut down ice making for a predetermined period of time and then automatically resume ice making. Preferred embodiments of the a water system comprise a water filter and the control system comprises a filter change indicator, whereby an indication is displayed after a predetermined condition is reached indicating that the water filter should be replaced. Also, the control system preferably comprises a sensor to determine the temperature of the liquid line and a program that controls operation of the condenser fan during a harvest mode based on the temperature of the liquid line. Further, the preferred control board is changeable so that it can be used to appropriately control different models of ice making machines, with a microprocessor determining different durations of freeze and harvest cycles based on the same sensor temperature, depending on the changed aspect of the control board. The harvest cycle duration is preferably controlled by measuring the temperature of the refrigerant leaving the condenser at a predetermined time before termination of the freeze cycle and using that temperature and a controllable factor to determine the desired duration of a harvest cycle. The duration of the freeze cycle and/or the harvest cycle are preferably determined by a microprocessor and based on i) at least one input from a sensor and ii) a manually entered modification input from a user interface.

A monitoring, control and feedback system for a refrigeration unit is provided that includes a wireless transceiver operably connected to the control circuitry of a refrigeration unit. The transceiver is operably connected to the central processing unit (CPU) of the refrigeration unit and receives signals from the CPU regarding the operation of the refrigeration unit. The transceiver wireless communicates these signals to a program or application stored and operating on a suitable u ser device that displays the signals illustrating the current operational parameters of the refrigeration unit on the user device while also enabling the user to control the operation of refrigeration unit remotely.
